bipod or improvised rest?

For my hunting field conditions, I use a 13 1/2" - 27" Harris bipod that allows me a steady shot from prone to sitting but will adapt accordingly, it's rare but if I need lower than 13 1/2", I'll use my pack as a rest.

+1 same here. If your going to use it in the field train with it at the range.

I think so. I am 5'11" and I can use the sitting model comfortably kneeling. I measured it once for a guy on the nosler forum and my barrel is 40" off the ground kneeling with the bipod comfortably. I shoot alot that way to get over vegetation in my hunting area.
